Namco Bandai Games has released two new games for the PlayStation Vita this week: Shinobido 2: Revenge of Zen and Touch My Katamari. Developed by Acquire, Shinobido 2: Revenge of Zen puts players into the role of Zen, a master ninja who can scales sheer walls, leap across rooftops, and sneaks silently towards prey to expertly dispatch them. Using the touch screen and rear touch pad, players will be able to mimic ninja actions such as throwing ninja shuriken and targeting grapple points.

Players wanting to get a taste of Zen’s deadly assassin skills in Shinobido 2: Revenge of Zen, can do so by checking out the free demo soon available on the PlayStation Store. Additional premium downloadable will also be available post-launch. The game is rated "M" by the ESRB and is available for a MSRP of $39.99.

Touch My Katamari uses both the rear touch pad and touch screen to stretch and squeeze their katamari ball through missions while building up a wardrobe for the King of All Cosmos himself!

The King has tasked his son, the tireless Prince, with rolling up an ever more enormous ball of weird and wonderful junk in order to win back the fans who’ve forgotten the glory of the cosmos.

A demo containing a tutorial and one mission scheduled to be available on PlayStation Network, plus additional downloadable content is scheduled post-launch. The game is rated "E 10+" for Everyone 10+ by the ESRB with a MSRP of $29.99.
